I'm currently using Ubuntu Server 16.04.2 in Virtualbox and I'm trying to set up a web server. It seems like my server or rather the network interface "enp0s3" doesn't have an IP address or an "inet addr", which, as far as I know, is necessary for the server to work.
This is an image showing my problem
What can I do to change that? Are there any special network adapters necessary? Also, does it work with "enp0s3"? Because in many other guides I've just seen "eth0". I know that this occurred in older versions of Ubuntu but I'm rather a beginner so I'm not very sure about the difference.
And a different question: Should I actually try to disguise some of the information given in the picture or is that no risk?
Thanks for helping!
